The molded parts in plastic material have been manufactured in PP or PE. These have also been manufactured same pieces in PA or PET. It has also been used as a second outer piece (6) portions of embossed surface metal tube raised.

Depending on the type of cover (1), the different parts of said cover (1) have been mounted, either as indicated in the description, or in an obvious way, namely:

- either fixedly to make them solidarity, particularly in rotation, for example when it is about the metal cover (3), the insert (4) and the mentioned one first outer piece (5), which can be particularly sympathetic  by means of adhesive layers.

- either by embedded or axial interlocking of the pieces, when it comes in particular to that second outer piece (6).

Depending on the type of scenery, the first mentioned (5) and second (6) exterior pieces have been decorated either before of the assembly, or after assembly, once it has been said cover formed (1).

We will describe here in more detail example 3 illustrated in figure 5, knowing that this cover comprises common features of the invention, which can be detailed and / or referenced in other figures.

The composite closure cap (1) of this example comprises a pouring device (9) which comprises in its part upper one flexible annular flange (90) and an inner skirt (91) Suitable for entering the neck (2) and snapping to the aforementioned neck, tightly, thanks to a plurality of fins (910).

The composite closure cap (1) comprises a metal cap (or "helmet") (3) provided with a metal skirt (31) comprising a crimping zone (36) of said cover metal around the neck, (figure 5 illustrates skirt 31 set in 36 'on the projection 210 of the counter-ring 21) and a weakening line (330), used as a means of first easy opening of said composite closure lid.

The composite closure cap (1) comprises a insert (4) in plastic material, integral with a top part (32) of the helmet (3), which said insert comprises a head of tightness (40) and an internally threaded skirt (41 '), here particularly thin, of axial height H I <H C.

The composite closure cap (1) comprises a first outer part (5), mounted to the metal cover (3), which it has a peripheral part of manual clamping (50) in diameter medium D_ {P}> D_ {M}, so that, when said cover of composite closure seals the aforementioned neck, a manual rotation of the said outer part activates that of said metal cover and that of the mentioned insertion, thus allowing the unscrewing of the cited composite closure cap and said opening neck.

The composite closure cap (1) comprises a second outer piece (6) mounted to the metal skirt (31) of way of covering and hiding the lower part (35) of said metal lid. This second outer part (6) is a moving part (61), which moves axially and presents, in relation to the metal skirt (31), two stable positions determined previously: a low position in which the moving part (61) leaves free access to the ring setting area of the metal skirt of the helmet, and a high position in which said movable part (61),  axially traced in the direction of the first outer part (5) after crimping, hide at least the crimped area (36 ') of the cited metal skirt. The moving part (61), in a high position, cooperates with the lower part (35) of the metal skirt (31) of the helmet (3) so as to remain supportive of the neck (2) after unscrewed from the aforementioned composite closure cover (1).

The positioning means (18) used to the second moving outer part (61) uses axial cooperation of axial locking means (64) and (631) carried by said moving part, and axial locking means (311) and (312) carried by the  metal skirt (31). This means of positioning could form a reversible interlocking means to ensure a passage reversible from one position, high or low, to the other position, respectively low or high. But here, the means of positioning (18) is designed in such a way that said second piece mobile exterior (61), after keeping in low position to facilitate access of the crimping elements over the area to set the metal skirt of the helmet, it is put in high position and remains locked in this high position, in order to prevent the access to the set area (36 ').

As illustrated in Figure 5, the second piece outside (61) remains high thanks to cooperation of the axial locking means (64) and (311). It remains in low position thanks to the cooperation of the blocking means axial (631) and (312). This axial locking means used for the low position allows the said second outer piece (61) remain in solidarity with the metal skirt (31) of the helmet (3) when The lid is not yet set on the neck. Figure 5 shows that the metal skirt (31) wears, just below the area of crimped (36) or from the crimped area (36 '), a first rod annular (37) whose two inclinations (311) and (312) act as means of interlocking, which the first inclination (311) serves, in high position, from irreversible interlock stop to a flange (64) of the moving part (61) and the second (312) serves, in position low, reversible interlock stop to the oblique wall incoming (631) of the upper end of said moving part (61).

Unscrewing the composite closure cap can be carried out, the first outer part remaining (5) solidarity of the upper part (32) of the helmet (3) and remaining the second outer piece (61) integral with the lower part (35) of the metallic skirt (31), itself solidary of the contraanillo (21) on which it is set.

The second outer piece (61) is in polyolefin, especially a polypropylene. It has not been opaque (metallization, lacquered, placed a set, etc.) in its part upper (63), so that it is transparent and possible see the weakening line (330) when said second piece Mobile exterior (61) is in high position. In a variant, for improve the transparency of the upper part (63), the second outer piece (61) is in polystyrene glass. Top (63) is provided with annular ribs (630) that facilitate the manual clamping of the second outer part (61).

The second outer piece (61) must slide over a distance large enough to reach its low position, so as to leave an access to the crimping zone wide enough for guards or other elements of crimping can reach the projection (210) of the counter ring (21) without disturb the other parts of the lid. This distance especially It is between 5 and 15 mm. As can be seen in Figure 2c, the low position may correspond to the arrival at the top of the lower end (611) of the second outer part (61) on the neck (2) of the bottle, which in this place is conical. In this case, the second outer piece (61), which has the shape of a cylindrical sleeve, must have an internal diameter especially greater than 1 mm with respect to the diameter of the lower part (35) of the metal skirt (31). Advantageously, said skirt metallic (31) is provided with a second annular rod (38), of radial height especially equal to 0.5 mm, which allows the second outer piece (61) slide along the shaft (10) staying centered.

The composite closure cap of this example 3 (Figure 5) comprises a pouring device (9) intended for facilitate the flow of the liquid, which comprises an annular flange flexible (90), and that is apt to move in solidarity with the composite closure cover (1), thanks to the insert (4), for rubbing contact on the axial projection (45) of the shutter (47) solidarity of the insertion (4). This pouring device (9) It also includes an inner skirt (91) suitable for cooperating with the inside the neck 2, thanks to at least one circular fin (910), in a way to sympathize with the neck (2) hermetically. The fins (910) are represented schematically here, "entering" into the glass and not tilted up.

On the cover of Example 4 (Figures 6a to 6c), it also finds a pouring device (9 ') that also meets the non-filling device function. It is also provided with a flexible annular flange (90) and which can be in solidarity with the insertion (4). It also includes an inner skirt (91) that cooperates with the interior of the neck (2) thanks to several fins circular (910), deformed by the pressure introduction of the device inside the neck (fig. 6a).

The seal is ensured by the action of the annular flange (470) of the shutter (47) that drives the placement of the flexible annular flange (90) over the edge (22) of the neck.

The composite closure caps of examples 4 and 5 (figures 6 and 7) have non-filling devices (8) and (9 ').

The non-filling devices (8) and (9 ') are intended to prevent any fraudulent refilling of the bottle by the neck (2). They are integral to the composite closure lid (one):

- the device (8) comprises a threaded part which allows to screw it onto the insert (4) (in this case, the fixation of the composite closure cap is no longer done on the glass ring: the external thread (20 ') of the neck corresponds to the device (8) irreversibly fixed to the neck).

- the device (9 ') that also has a pouring device function as in example 3 is connected to the insertion (4) by the inclination of a rubbing contact on an axial projection (45) of the shutter (47) integral with the insertion (4).

These devices are fixed to the neck (2) on the moment of the encapsulation operation and remain fixed at quoted neck when said composite closure cap (1) is To stop.

The non-filling device (8) of example 5 understands:
